Since visiting the Napa Valley as a college student in 1973, Peter Thompson set his sights on producing world class Napa Valley Cabernet Sauvignon. In 1995, after a two and one-half year search for the ultimate mountain vineyard site, Peter selected the property at 2000 feet atop Diamond Mountain. Having purchased undeveloped land with unlimited potential, Peter assembled a team consisting of viticulture and enology specialists to plan and execute planting of a state of the art vineyard. 13 acres were carved out and planted to Cabernet Sauvignon, Cabernet Franc and Petit Verdot. The vineyard was christened Andrew Geoffrey Vineyards after Peter’s two sons, Andrew and Geoffrey, and currently enjoys a reputation for producing mountainside grapes and Cabernet Sauvignon wine of unprecedented quality.
